The Green Bay Packers have confirmed that the NFL will interview Clay Matthews and Julius Peppers, who were named in an Al-Jazeera America report linking them to performance-enhancing drugs.
The interviews are expected to take place in Green Bay when training camp opens next week.
"The league is pursuing that," president Mark Murphy said. "I know there's been some resistance from the NFLPA about the credibility of some of the sources there, but I don't think we know much more than that."
Matthews and Peppers have denied the assertions of the Al-Jazeera report.
The initial report came out last December and linked several NFL players, including Peyton Manning, to HGH and other drugs.
"I think it's bulls---, to be completely honest with you," Matthews said back in December. "It's 100 percent falsified, fabricated information. I don't who this guy is. I couldn't tell you what he looks like. I've never talked with him. I've never communicated with him. So for him to bring my name up like that, which appears to be out of thin air, it's bulls---, for a lack of a better term.
"I work hard on my reputation, and really that's all I have," Matthews added. "For seven years, I've worked my ass off. For this guy to say those type of things, it's just not true, and especially for him to recant everything that he said, too, I think it really just goes to show the [type of] source he is, as well. The truth will come out, and I'm not worried about it, because I carry myself a certain way, and that is the right way."
